Benefits of technology
The present invention is a drug delivery device that can be worn as a patch-style pump and is controlled through wireless telemetry. The device is designed to deliver medication to patients with Type I or Type II diabetes in discrete boluses, replacing multiple daily injections. The device is small and unobtrusive, with a flexible design that reduces discomfort and interferes with activities. It is fully controllable via remote telemetry and includes safety interlocks to prevent unauthorized telemetry or spurious RF signals. The technical effects of the invention include improved accuracy and convenience for patients, as well as improved control and flexibility for the patient to manage their blood sugar levels.
Problems solved by technology
Diabetes is a major health concern, as it can significantly impede on the freedom of action and lifestyle of persons afflicted with this disease.
Additionally, improper administration of insulin therapy can result in hypoglycemic episodes, which can cause coma and death.
For many diabetics, this results in having to receive multiple daily injections of insulin.
Due to the debilitating effects that abnormal BG levels can have on patients, i.e., hyperglycemia, persons experiencing certain symptoms of diabetes may not be in a situation where they can safely and accurately self-administer a bolus of insulin.
Moreover, persons with active lifestyles find it extremely inconvenient and imposing to have to use multiple daily injections of insulin to control their blood sugar levels, as this may interfere or prohibit their ability to engage in certain activities.
For others with diabetes, multiple daily injections may simply not be the most effective means for controlling their BG levels.
Because the pumps are worn on the patient's body, a small and unobtrusive device is desirable.

Embodiment Construction
[0026]FIGS. 1A-3 illustrate a drive mechanism 100 of an infusion pump according to an exemplary embodiment of the present invention. Generally cylindrical in shape, the drive mechanism 100 includes a proximal end 102, a distal end 104 and a combined motor and gearbox (hereinafter referred to as a “motor 106”) operatively coupled to a lead screw 108 that is configured to engage a piston 110. The proximal end 102 of the drive mechanism 100 is compliance mounted (i.e., has a “floating” mount) to an internal surface (not shown) of a housing of a drug delivery device such as, for example, an insulin pump. A compliance mount allows the motor housing to turn slightly in response to high motor torque during motor startup. The distal end 104 of the drive mechanism 100 is configured to engage a plunger 111 that is slidably inserted into a drug reservoir 112 (or cartridge) of a drug delivery device. The drive mechanism 100 is coaxially aligned or “in-line” with the axis of travel of the plunge...

Described is novel system for delivering medication to a patient via an infusion pump. The infusion pump includes mechanical means for delivering medication that are locked and unlocked via a remote control device. The remote control device is configured to be programmed with a desired dosage of medication and to unlock the infusion device to permit the patient, user, or healthcare provider to mechanically deliver only the desired amount of medication by turning a dial. Once the desired dosage of medication has been manually delivered, the remote control locks the infusion device.
Description
RELATED APPLICATIONS[0001]This application claims priority to U.S. Ser. No. 61 / 840,533 filed Jun. 28, 2013, which application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates, in general, to drug delivery devices and, more particularly, to a drug infusion device that may be worn as a patch-style pump configured to deliver medication to a patient in discrete boluses. The disclosed device may receive commands from a remote device via wireless telemetry and includes a safety interlock to lock-out, or block, remote instructions.BACKGROUND OF THE INVENTION[0003]The use of drug delivery devices for various types of drug therapy is becoming more common as the automated infusion of a drug may provide more reliable and more precise treatment to a patient.[0004]Diabetes is a major health concern, as it can significantly impede on the freedom of action and lifestyle of persons afflicted with this disease. Typically, treatment of the more severe form...
